Carbon is essential for life on Earth, found in all living things and regulating temperature and energy. The carbon cycle involves the continuous movement of carbon between storage reservoirs through processes like photosynthesis in plants and consumption by animals. Human activities, particularly in various industrial sectors, significantly impact this natural cycle by emitting carbon dioxide.

1. The Carbon Cycle:

2. What is Carbon?
• Carbon is the chemical
backbone of life on Earth.
It is found in all living
(organic matter) things on
Earth.
•It can be found in rocks, oceans,
atmosphere. Carbon compounds
regulate the Earth’s temperature,
make up the food that sustains
us, and provide energy that fuels
our global economy.

3. The Carbon Cycle:
• The same carbon atoms
are used repeatedly on
earth, cycling between the
earth and the atmosphere.
• Carbon moves from one
storage reservoir to
another through a variety
of mechanisms.

4. Plants and Carbon Cycle:
• Carbon moves from one storage reservoir to another through a variety of mechanisms.
Plants pull carbon dioxide from
the atmosphere into the
biosphere, using it to make
food through the process of
Photosynthesis. The carbon
becomes part of the plant and
is stored as Starch the leaves,
stems or roots of the plant.
Thus entering the food chain.

5. Animals and Carbon Cycle:
• Carbon moves from one storage reservoir to another through a variety of mechanisms.
.
When organisms eat plants, they take in the
carbon and some of it becomes part of their
own bodies. All Animals that eat plants digest
the sugar molecules to get energy for their
bodies. Respiration, excretion, and
decomposition release the carbon back into
the atmosphere or soil, continuing the cycle.
When humans consume plants and animals
we add to this cycling of matter.

• Carbon moves from one storage reservoir to another through a variety of mechanisms.
Human Impact
The primary industrial
activities that emit carbon
dioxide and affect the
carbon cycle are petroleum
refining, paper, food and
mineral production, mining
and the production of
chemicals.
